Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single welding apparatus is used on a robot arm, then equipment cost is reduced, but welding time increases significantly
Solution Approach 1:
The welding apparatus is segmented into a fixed welding machine and multiple moving welding machines that can be selectively positioned along the guide plate. This allows one welding station to perform multiple welding operations at different locations, effectively replacing the need for multiple robots while maintaining reduced welding time.
Solution Approach 2:
The welding apparatus incorporates movable welding machines that can be selectively positioned along the guide plate using a transfer cylinder. This dynamic repositioning capability allows the same welding apparatus to service multiple welding points, increasing productivity without requiring multiple fixed welding stations.
2Productivity
If multiple robots are installed to perform simultaneous welding, then welding time is reduced, but equipment cost and spatial occupancy increase
Solution Approach 1:
The welding apparatus is designed with multi-functionality, where a single fixed welding machine and movable welding machines can service multiple welding points along the guide plate. This universal design allows one apparatus to perform the work of multiple dedicated welding stations, reducing equipment cost while maintaining high welding speed.
Solution Approach 2:
The invention merges the functions of multiple welding stations into a single integrated apparatus. The fixed welding machine and movable welding machines work together on one apparatus, combining the capabilities of multiple robots into one system that reduces both equipment cost and spatial occupancy.
3Productivity
If multiple robots are used for simultaneous welding, then welding efficiency improves, but energy consumption increases
Solution Approach 1:
The welding system is segmented so that only the necessary welding machines are activated and positioned for each specific welding task. This selective operation of individual welding machines on a single apparatus reduces overall energy consumption compared to running multiple robots simultaneously, while still achieving high welding efficiency.
4Device complexity
If welding is performed at multiple points sequentially with one apparatus, then equipment cost is reduced, but welding time increases
Solution Approach 1:
The movable welding machines can be quickly repositioned along the guide plate using a transfer cylinder, enabling the single apparatus to service multiple welding points with minimal repositioning time. This dynamic repositioning capability reduces the time penalty associated with using one apparatus for multiple welding locations.
